[Research][Functional Test] why setDefaultAbsoluteRange is not robust for Discover in plugin_functional test

[ananzh]

Describe the bug

• First of all, I have run couple of times locally and every time I could see two panels open. The reason is that this checking function opens the panel and selenium not close it in time. Check my screen record.
  

  OpenSearch-Dashboards/test/functional/page_objects/time_picker.ts

  Line 139 in 1e980fa

  await this.showStartEndTimes();

private async showStartEndTimes() {
      // This first await makes sure the superDatePicker has loaded before we check for the ShowDatesButton
      await testSubjects.exists('superDatePickerToggleQuickMenuButton', { timeout: 20000 });
      const isShowDatesButton = await testSubjects.exists('superDatePickerShowDatesButton');
      if (isShowDatesButton) {
        await testSubjects.click('superDatePickerShowDatesButton');
      }
      await testSubjects.exists('superDatePickerstartDatePopoverButton');
    }

issue.mov

• Sometime time is not set. I still see the original time not input time.
• Need to modify test_suites/doc_views_links because currently we open links in new tab
• Need to modify test_suites/doc_views because we uses data grid for table
